How do you access properties of a QML component in C++?

Okay so I understand you can connect signals and slots between QML and C++ objects and how to pass stuff generated in C++ to QML but how would I go about calling property of QML object for use in C++. Basically what I am trying to do is take text input from the TextInput component in QML and use it to set the currentPath() of an object which in the QDir class. I am sure I messed up a lot syntax and stuff there but I am pretty new to this.

I was thinking of doing something like
@
QObject *object = view.rootObject();
QObject textIn = object->findChild<QObject>("textIn");
@
and then calling text property like so and using QString to make a string.
@
QString textholdervariable(textIn.text());
@
and then doing the following to set my QDir path
@
QDir dir;
QDir::setCurret(textholderviable);
@
But this doesn't work as I get following error

request for member ‘text’ in ‘textIn’, which is of non-class type ‘QObject*’

Anyone know the proper way to go about retrieving properties of QML objects for use in C++?
I would also be okay with being able to set the a variable in QML equal to some variable and then being able to call that in C++.
I would also be okay with being told I am asking a stupid question and what I am talking about is impossible or there is a better way to do such a thing any help would be great.

The last post helped quite a bit I am having trouble using it though can't seem to find any examples of people actually using it so not sure how I am supposed to implement that piece of code. In the form it is presented it isn't working for me. Do I need to use Q_PROPERTY macros or anything to make it work? Not really sure if what I need to make it work.

i have a similar problem. i managed to set a value from c++ in my qml file. the value is the x position of a qml rectangle, but when i change the value in c++ the rectangle isnt moved. What am i doing wrong?

How should we know, if you are not showing us what you are actually doing?

and then to call the property just do
@
property.read()
property.write()
@
and you can even do stuff like property.read().toString etc. this is what I was really looking for I think but thanks for all the help wouldn't have been able to find it without the leads.

You still need stuff like
@
QObject object = object->findChild<QObject>("rect");
@
to use this though

What is the delete statement doing on line 6 of your code? What do you expect to happen if you first set a property, and then immediately delete the object?

What you are doing here, is creating an object, setting a property on it, and then immediately disposing of it again. That seems like a rather useless thing to do. Instead, you should try to find the object you wish to manipulate, and then modify its properties. Or, perhaps better from a QML/declarative way of thinking kind-of-perspective, you should create a QObject derived object, give it properties for the position, insert it into your QML environment, and bind to these properties.
